Questions with "le ma"

Asking questions about completed actions will involve using both 了 and 吗. These are simply added to the end of a sentence or statement. This means you might see questions with 了 and 吗 in different structures.

A general structure is:

Subject + Verb + Object + 了吗

Some examples:

• 你 去 了 吗？
• 你 吃饭 了 吗？
• 你 看 了 吗？

Another common structure is:

Object + Verb + 了吗

• 北京 去 了 吗？
• 饭 吃 了 吗？
• 电影 看 了 吗？

Notice that in this one the object is introduced first as a topic.

Finally, please notice that this pattern is nothing more than the combination of the Expressing Completion with "le" pattern and the Yes/No Questions with "ma" pattern.
